The utility model provides an anti-ultrahigh detection device of a forklift, and aims to solve the problem that when an infrared sensor of existing anti-ultrahigh detection equipment of the forklift performs anti-ultrahigh detection on goods on the forklift 100, the detection accuracy is poor due to limited detection range.

Referring to fig. 1 to 3, in an embodiment of the present utility model, the fork lift anti-super high detection device includes:

the forklift 100 comprises a forklift mast 110 and a fork frame 120, wherein the fork frame 120 is arranged on the forklift mast 110, and the fork frame 120 is used for placing goods;

the laser sensor 200 is provided with a mounting position on the forklift mast 110, the laser sensor 200 is mounted on the mounting position and is electrically connected with the control assembly 130 of the forklift 100, and the laser sensor 200 is used for emitting a plurality of fan-shaped laser beams and forming a detection plane in the direction of emitting the laser beams;

the warning component 500 is disposed on the forklift 100 and electrically connected to the control component 130, and the warning component 500 is used for performing an ultrahigh alarm.

It will be appreciated that the forklift 100 is an industrial truck, and refers to various wheeled trucks that handle, stack and short-range transport operations of pallet loads, and generally includes a truck body, a forklift mast 110 and a fork carriage 120. Wherein, fork truck portal 110 locates the automobile body, and fork truck portal 110 is located to fork truck frame 120, and fork truck frame 120 is used for placing the goods of waiting to carry. However, when the height of the cargo exceeds the preset height range of the forklift 100 before the forklift 100 carries the cargo, the cargo directly affects the visual range of the user driving, so that there is a potential safety hazard in driving. Therefore, in order to reduce the probability of the above-mentioned potential safety hazard, it is an essential measure to prevent the self-height of the cargo from being excessively high.

However, in the existing forklift anti-ultrahigh detection device, an infrared sensor is usually disposed at a certain fixed height position on a forklift mast 110, and an environmental condition within a preset distance is detected by infrared light emitted by the infrared sensor. When the infrared light emitted from the infrared sensor detects the occurrence of the goods within the preset distance, the fork lift prevention detecting apparatus determines that the goods on the fork carriage 120 have been lifted. However, in this case, since the infrared sensor usually emits an infrared light to detect, the detection range of the visible infrared sensor is limited, the accuracy of preventing high detection is not good, and it is not possible to accurately determine whether the maximum height of the goods on the forklift 100 has exceeded the preset height range, and there is still a possibility of causing a blind area of sight to the user, so that there is a potential safety hazard.

In this regard, since the laser sensor 200 is a sensor that detects by using a laser technology, it can realize contactless remote detection, and has the characteristics of fast speed, high accuracy, wide detection range, strong light and electric interference resistance, etc. compared with an infrared sensor, the fork truck super-high prevention detection device of the present application includes the laser sensor 200, and the above-mentioned problem is improved by the laser sensor 200.

Specifically, the forklift mast 110 of the forklift 100 is provided with an installation position, and the installation position forms a certain height with the placement surface of the forklift anti-ultrahigh detection device of the application. The height here refers to the maximum height of the fork truck for preventing the fork truck from being raised by the height-preventing detecting device, for example, 2 meters, and is specifically set according to the height of the fork truck 100 or the height of the carried goods. The laser sensor 200 of the present embodiment is disposed at the mounting position, and the connection manner of the laser sensor and the forklift mast 110 may be glue joint, clamping joint, or the like. The laser sensor 200 is electrically connected with the control assembly 130 of the forklift 100 through a wire, and is used for emitting a plurality of fan-shaped laser beams in real time when the forklift anti-ultrahigh detecting device is in a starting state, and the plurality of laser beams form a detecting plane in the direction of emitting the laser beams. It can be seen that the detection range of the detection plane is far greater than that of the infrared sensor, so when the detection plane detects that the cargo is present, the laser sensor 200 will give feedback to the control component 130 in real time, and the accuracy of preventing high detection will be higher.

In order to enable the user to know the detection condition of the laser sensor 200 on the goods in real time, the fork truck anti-ultrahigh detection device of the application further comprises a warning component 500. Alternatively, alert component 500 may employ, but is not limited to, a display component, a voice component, an alert light, and the like. The alert component 500 of the present embodiment is implemented using a voice component. Specifically, the voice component may be disposed at any position of the forklift 100, and the connection manner between the voice component and the forklift 100 may be gluing, clamping, or the like. The voice component is electrically connected to the control component 130 by wires. When the control component 130 finds that the goods on the fork frame 120 are ultrahigh according to the feedback signal of the laser sensor 200, the control component 130 synchronously outputs a voice control signal to the voice component, so that the voice component sends out voice type ultrahigh reminding, the user can adjust the height of the goods, and the potential safety hazard that the user drives the fork truck 100 to carry the goods is reduced.

The forklift anti-ultrahigh detection device provided by the technical scheme of the utility model comprises a forklift 100, a laser sensor 200 and a warning component 500. The forklift 100 comprises a forklift mast 110 and a fork frame 120, wherein the fork frame 120 is arranged on the forklift mast 110; the forklift mast 110 is provided with an installation position, and the laser sensor 200 is installed at the installation position and is electrically connected with the control assembly 130 of the forklift 100; the warning module 500 is disposed on the forklift 100 and electrically connected to the control module 130. The technical scheme of the utility model solves the problem of poor detection precision caused by limited detection range when the infrared sensor of the existing fork truck anti-ultrahigh detection equipment performs anti-ultrahigh detection on the goods on the fork truck 100.

Alternatively, laser sensor 200 may include, but is not limited to, laser transmitter 210, laser receiver 220, and the like. The present embodiment takes as an example two main working components in the laser sensor 200, namely the laser transmitter 210, the laser receiver 220 lasers.

When the fork truck anti-over height detection device is in a start-up state, the laser transmitter 210 emits a plurality of fan-shaped laser beams in real time, and the laser beams form a detection plane in the direction of emitting the laser beams. At the same time, the laser receiver 220 acquires the laser beam in real time and outputs a corresponding feedback signal to the signal input terminal of the control assembly 130 through the signal output terminal. When the control component 130 finds that the cargo on the fork frame 120 exceeds the preset height range through the feedback signal, the control component 130 will control the component 130 to synchronously send out a warning control signal to the warning component 500, so that the warning component 500 can perform an ultrahigh warning.

However, in order to avoid shielding the light emitted from the laser sensor 200 by the mounting groove 300, the other end of the laser sensor 200 extends out of the mounting groove 300.

Referring to fig. 1 to 3, in an embodiment of the present utility model, the laser sensor 200 is fixed in the mounting groove 300 by glue 400.
